Application filed February 7, 1928. Serial No. 252,4;77.

Our invention relates to apparatus for ginning cotton and it .has particular relation to an improvement of a portion of the apparat-us that will facilitate the removal of ginned cotton therefrom. v

One object of the invention is to provide a device that Will remove ginned cotton from 'a ginning roller Without tangling or matting the cotton. l

Another object of the invention is to provide a device that will remove ginned cotton from a ginning roller in such manner that Waste lint is reduced to a minimum, and, at the same time, so affecting the lintas to facilitate its subsequent handling. .Y

Heretofore, cotton gins, especially those employed for ginning long` staple cotton, were provided with stationary b-rushes that were mounted adjacent the ginning rollers for removing the lint therefrom. While these brushes performed their function to a certain extent, they caused the lint to become matted and tangled, and considerable quantities of the lint adhered to the ginning rollers. Therefore, samples .having the'desired characteristics Were difficult to obtain. Also, by the employment of brushes so-called backlashing occurred Which caused considera- :ble waste of the lint cotton. This Waste sometimes amounted to at least per cent vof the output of the ginned cotton.v An additional disadvantage resulting from the operation of the brush type roller. Was that' the rollers became overheated. Y,

By employing an apparatus according to this invention, the disadvantages referred to are obviated. The invention involves the application of a roller having a uted or grooved surface, which is mounted adjacent the ginning roller and is provided With bearings so constructed that the position of the roller can be varied in both vertical and horizontal directions, in order that the rollers may assume their proper relation to each other.

Suitable driving connections are provided inV conjunction with the mechanism that forms a part of a conventional cotton gin for operating` a device embodying the invention. By utilizing. a device of this kind, the ginning elements of the apparatus can be properly observed or inspected Without vinterference from such obstaclesas rollers or brushes hav ing matted or tangled lint cottonthereon.

For a better understanding of the invention, .reference may now be had to the accom-` panying drawings, forming a` part of this` having a horizontally disposed crank shaft 12, mounted in the lower portion vthereof and driven by a suitable source of power (not shown). One end of the' crank shaft rigidly supports a relatively large grooved pulley 13. A belt 14 is trained about the pulley 13Tand about a relatively smaller pulley. 15 thatA is rigidly secured to one end portion of a horizontally disposed shaft 16. Journal bearings 17 support the shaft 16 adjacent the endportions thereofand have offset portions 18, through which bolts 19 are disposed and secured. These bolts extend throughslotted portions 22 of angular brackets 23and are adjustable horizontally'therein. A verticalA portion 24 of the bracket is provided With openings 25 for the reception of bolts 26 that are threaded'into an end portion of arms or brackets 27 rigidly secured to, and forminga part of, the framell. 'A pluralityof the bolt openings 25Which are preferably elongatein form, are arranged `in parallel relation, thus providing means for vertically adjusting the position of the bracket 23.

A roller 28, having fluted portions or grooves 29 formed in the surface thereof is rigidly mounted upon the shaft 16 between the brackets 23. Preferably the grooves 29 are spaced and extendlongitudinally of the roller 28, as shown, although it Ais apparent that they may assume other forms orshapes.

The arms 27 are provided with horizontal surfaces 32, upon each of Which aV bearing support SBVis slidably adjustable by means of a bolt 34 having one end thereof secured to the bearing'support, as indicatedat 35,

and having its 'other end portion extending 1 through the frame 11 and provided with an adjusting nut 36; Bearing blocks 37`vvhich can be tightened by means of bolts 38,'support a driven Vshaft39 in; spaced relation Y rollers 28 and 42 are rotatably driven in the same direction, but the roller 42 is normally driven at a rate of approximately 140 R. l. M. While the roller 28 is driven at the rate of approximately 1200 R. P. M.

The ginning operation is performed by a mechanism 43, which is actuated by means Yof crank arms 44 driven bythe vshaft 12.

Since this mechanism does not constitute a part of the invention, a detailed description thereof is not necessary. After the lint, indicated at 45, has been separated from the cotton seed, the roller 42 tends to move it away from the mechanism 43. The grooved roller28 which rotates at a relatively high rate ofr speed prevents the lint from adhering to the roller 42 and also prevents it from becoming mattedand tangled. By the rapid rotation of the roller 28, the grooves therein serve aspartial vacuums, thereby facilitating the removal of the lint from the roller 42.

Thus, during ginning operations the roller 28 causes continuous removal of the lint from the roller 42.4

From the foregoing description, it Will be apparent that the invention constitutes a marked improvement over the types of devices previously employed for ginning cotton and that the expense of yoperating such apparatus can be materially reduced by practicing theinvention.

Although We have illustrated only one Y form which the invention may assume and have described in detail but a single application thereof, it will be apparent to those skilled in the art thatit is not so limited but` that various minor modifications may be made therein Without departing from the spirit of the invention or from the scope of the appended claims. Y

What We claim is i 1. The combination With a machine having means for ginning cotton including a driven ginning rigid roller, of a second roller mounted upon the machine adjacent the ginning roller, the second mentioned roller having grooves formed in itssurface longitudinally thereof.

2. The combination With a machine having means for ginning cot-ton including a driven ginning roller, of a second rigid roller having grooves formed in its surface longitudinally thereof, a support for the rollers, and bearing brackets supporting'the second mentioned roller upon the support, said bracket being vertically adjustable along the support and a portion ofthe bracket carrying the second mentioned roller being horizontally adjustable upon the remaining portion of the bracket.

3. The combination With a machine having 'means for ginning cotton including a driven ginning roller, of a second driven rigid roller geared to rotate at a materially greater speed than the 'ginning roller, the second mentioned rollerhaving grooves extending longitudinally in the surface thereof, a support for the rollers, and bearing brackets supporting the second mentioned roller upon the support, each of said brackets being composed of btvvo parts, the first partbeing vertically adjustable on said support andthe second part being horizontally adjustable on the first part.

In Witness whereof, We have hereunto signed our names.
